Traffic Generator with Statistical Capability

I am looking for a traffic generator that I can use to simulate Video traffic (Qos, Packet Size, Continuous Streaming, etc.)
across the network. IP SLA UDP jitter is close but it is not a continuous stream and from viewing the documentation I'm not sure
the timeouts and frequency can be adjusted to give a continuous stream. So does anyone know of a traffic generator (software based)
that I can load on two laptops where on is the source and the other the receiver where I can pull statisitcs for latency, jitter, and lost packets?
Thanks for your help...

I have used iPerf for similar type testing:

Statistical Forecast not saved when generated with background planning job

Hello All,
The system I am working on is SCM 5.0 Support pack 15.
When I execute the planning job in the background to generate a statistical forecast, the job completes sucessfully, I have a spool that shows the forecast profile was executed (Auto Mod 2) with the appropriate model messages and the last two messages are 'Data saved successfully' and 'No data has been changed; data must not be saved', but when I go into interactive planning to view the forecast, there is no forecast in my key figure.
My planning area has the forecast settings maintained for Statistical Forecast, Corrected History, and Ex-Post Forecast key figures. My forecast profile is looking at the History key figure and Statistical Forecast key figure. My time series has been initialized for 36 months of History and 18 months of forecast. My planning book is set to have the Statistical Forecast Key figure as output only. My activity and planning job are set to execute in the appropriate planning book (in order to see the forecast alerts I have selected) with the specific selection profiles (no navigational attributes), and the aggregation level set (no navigational attributes).
The only way for me to see a forecast is to change the Statistical key figure setting in the planning book to output/input, execute the forecast job in the background, and then go into interactive planning. Am I missing something? Any help you could provide would be greatly appreciated.
Regards,
Roxane H.

Hello Senthilrajan,
I have executed the forecast in the foreground using the same planning book as the background job and same forecast profile (Auto Model 2)with a selection from the batch run (pulled a selection from the spool list) and it generated a forecast with the same messages as my background job except for the last two lines (Data saved successfully and No data has been changed, data must not be saved) that I was able to copy back into interactive planning. I then used this selection in the background job to execute the forecast in the background and did not see a forecast in interactive planning and received the same messages as before -
Data saved successfully
No data has been changed, data must not be saved
The reason we run the forecast in this book is to allow our Demand Planners to view the forecast alerts by book and/or selection directly in interactive planning instead of having to get their from the Alert Monitor. It has worked in the past and is currently working in the same environment just with a different planning book, selections, forecast profiles, and data. It generates a forecast with no 'No data has been changed, data must not be saved' message and the forecast is written in the key figure and is viewable in interactive planning with out manipulating the key figure to be input/output (it is set to output only).
Any further assistance you can provide would be greatly appreciated.

Very high data traffic generated by Nokia Messagin...

Is anyone else seeing really high data use on their phone log following last week's Messaging outage?
Up until last week's outage, the data traffic generated by Messaging was about 5kb an hour (with no new emails sent or received). Presumably this small amount of data traffic results from the Nokia email server "pinging" the phone periodically to keep the connection open.
But after last week's outage and issues with passwords being requested etc etc, I saw that the data traffic generated by the Messaging app has gone through the roof - about 400 - 500kb an hour! Again, this is with no new emails sent or received - so theoretically is just the server pinging the phone to keep the idle connection open!
I reinstalled Nokia Messaging on my phone (E61i) - no difference - the data generated by the Messaging app is still 400 - 500 kb an hour (it stops when I take Messaging offline).
I have friends roaming in Ireland and their phone has had the same problem - the data traffic generated by their Messaging app is sky high and they have had to shut it down because of the high cost of data whilst roaming.
I also newly installed Messaging on another phone (N95) that I have, using a brand new email account and a new T-mobile SIM card, and guess what - that phone also has sky high data traffic due to Messaging.
What is going on?? Can someone at Nokia Messaging please sort this out? Anyone roaming with Nokia Messaging enabled is facing hugh data charges from their network.

The data traffic occurs in phones which are on a home network (mine in the UK) and on a roaming network (my friends traveling in Ireland). Interestingly, I've now checked with another friend who is roaming in Italy and they also use Messaging but haven't seen any high packet data issues with their phone.
The data traffic shows up in the Packet Log, as well as on the actual T-Mobile network account (plus the charges for the data!) Accessing a T-Mobile UK account online shows all packet data use - in this case, 120-150 kb every 15 minutes, whereas before last week it was 1-2kb every 15 minutes.
When I "Go Offline" with Nokia Messaging, the high data traffic stops, both on the Packet Log and network account, so I am 100% certain this is due to Messaging.

Re: How to disable MIG 7 Traffic Generator in simulation

Hi Everyone,
I was wondering how can I disable vivado traffic generator in simulation?
I have fine tune my DDR channel and need to disable traffic generator for simulation purposes, however, I don't see any option in MIG7 GUI interface, or any parameter that I can pass to traffic generator from my top level simulaion file to stop traffic generator for issuing command and putting random rd/wr data on my DDR bus.
Any idea?
Thanks,
Mike

Hi,
If you generate the IP alone there will not any tarffic gen, only example design comes with tarffic gen(right click on .xci and choose example design)
So while generating the IP there is no GUI option to disable traffci gen.
But if you attempt to link user deisgn top with memory model then you have to be ultimately careful in passign the parameters and mapping the signals
instead if you are running MIG example design simulation but wanted to drive your own tarffic, you can simply commet out tarffic gen in example_top and have your own fsm for driving the MIG user intefrace.
Hope this helps

Java SMTP Component (With Attachment capability)

Hi All!
I would like to ask regarding SMTP in java with the capability to attach microsoft excel files and txt file.
I need to use an html file also as the message for the mail (This is what the recipient will be reading), and need to attach excel files and the text files that I generated.
I previouly tried jakarta commons net smtp but I was not able to make some attachments to the mail and cannot use html file as for the mail.
Any idea of another smtp java component which is easy to use and has these features and most of all... free to use?� (or with cracks)
Thank you and God Bless,
MaDz

QoS Marking Traffic Generated by Network Device

I am working on defining QoS configuration standards for Catalyst 3750, 4500 and 6500 platforms. I would like to provide preferred treatment to some of the protocols commonly used for network management (i.e. telnet, ssh, etc...). I have no issues with classifying and marking traffic generated by a NMS or PC connected to a switch but I can not figure out how to classify and mark traffic generated by the switch itself. It won't do any good if traffic from the NMS or PC to the device is preferred but the response from the device is unmarked/best effort.
The only way that I can see to do this is to apply an input policy on the upstream device to classify and mark the network management traffic. I would prefer to do it on the device itself. Does anyone know if that is possible?
I'm assuming that any traffic generated by the switch would be ignored by an output policy, similar to the way that traffic generated by the device will by-pass access-lists. Even if this is a bad assumption the 3750 does not support output policies, so I'd still be stuck there.
It was suggested that I look into applying the policy to the control plane however on the platforms that options is available, policies can only be applied to the input. Which I believe is the wrong direction.
Anyone have other suggestions on how to accomplish this or is this a lost cause?

You can use local PBR to do this. Check out the local policy-map

Network Traffic Generator

Hi all
Could anyone suggest me a good Network Traffic Generator software (Free ofcourse or cheap ones) in windows platform? I am trying to setup a network where I can test and analyse the issues with VoIP packets under heavy traffic conditions. Please suggest!! I am struggling to find one. Thanks.

Hi ADITYA
Can you find the below?.
1- For traffic generation Windows is pretty bad, especially UDP traffic at any decent rates.
2-I would recommend the IP SLA feature in IOS to simulate VoIP and the statistics it generates are very good.

3- You can also check the following also :

ACLs never apply to traffic generated by the router

http://www.ciscopress.com/articles/article.asp?p=174313&seqNum=4&rl=1
"Another special note on Cisco ACLs is that ACLs never apply to traffic generated by the router. So, even if you have an inbound and an outbound ACL on a router denying all traffic, the router will still be able to send any packet it wants; the return packet, however, will be blocked as usual".
Is it (the return packet, however, will be blocked as usual) the case all the time ? if it is the case could you please explain ?

Thanks Rick,,,I need some clarification about the below scenario please:
suppose I have got R1 (one of many routers) with two interfaces serial0/0 and e0/0,,,the ip address for serial0/0 192.168.0.1/24
the ip address for e0/0 172.16.0.1/16.
R1(config)=access-list 101 deny ip any any
R1(config)#interafec serial 0/0
R1(config-if)#ip access-group out
R1(config)=access-list 150 deny ip any any
R1(config)#interafec fastethernet 0/0
R1(config-if)#ip access-group in
Now we satisfied the condition which it says: "where there is an outbound ACL and an inbound ACL and they both deny all traffic".
1- ((The inbound ACL will deny all traffic)).
This is obvious because any packet trys to enter the router R1, the ACL will check both ip addresses for the source (any) and destination (can be one of the interfaces belong to R1),,,,because it match the condition for ACL, it will be dropped.
2- ((In this case the outbound ACL can deny transit traffic, but can not deny packets generated by the router which will be transmitted)).
This first paragraph (In this case the outbound ACL can deny transit traffic) is fine,,,the second one which is : " but can not deny packets generated by the router which will be transmitted",,,,,,,my understanding is this when packets generated by router R1, these packets have got source ip address and destination ip address.
The source and destination ip addresses still matching the condition of ACL , why should't it be
denied ?

Radio button on a from generated with PL/SQL procedure

Hi,
I have a form generated with PL/SQL procedure. This procedure calls another procedure on 'Submit'. If I select value for the radio button, it works fine. But if no value is given to the radio button on the form, it gives error. Is the radio button mandatory field by nature? or do I need to give default value some how? How do I make the radio button optional? so that I can call the next procedure without passing the param.
Create or Replace PROCEDURE OBM_PROCEDURE
htp.formOpen(OWA_UTIL.GET_OWA_SERVICE_PATH || 'process_obm');
htp.Print('Admin ');
htp.FormRadio('p_access_level','A');
htp.Print('Doc ');
htp.FormRadio('p_access_level','D');
htp.formSubmit(cname=>'p_button', cvalue=> 'Submit');
=================================================================
Create or Replace PROCEDURE PROCESS_OBM
(p_access_level VARCHAR2,
p_button VARCHAR2)
htp.Print('p_access_level ');
Thanks!

Hi
The parameters of the called procedure should have defualt values like this
create or Replace PROCEDURE PROCESS_OBM
(p_access_level VARCHAR2 default 1,
p_button VARCHAR2 default null
htp.Print('p_access_level ');
Thanks,

Project System Cash Management in combination with statistical WBS element

Hi,
within a customer project, we have to solve the following issue:
Customer runs projects and statistical projects in combination with internal orders.
We want to use the PS Cash Management for planned and actual payments.
With statistical projects we have the following problem:
Invoice and actual payments will be processed with the transaction CJFN.
Actual payments are shown only on the internal order (transaction CJIA), but not on the statistical WBS element.
We want the information about the actual payments with in the project system reporting (S_ALR_87013574).
Projects, not flagged as statistical will deliver the expected results.
Many thanks for your ideas, to solve this problem.
Steffen

are u posting to some other cost object also. normally they wud have to be posted to a COPA also with the cost element being 11 category.
the wbs will receive the statistical posting, so there needs to be a real object also.
see whether the real object is getting derived.
the system is nt finding the real object and trying to post with the WBS in real, but since its statistical, the error.
any other calrifications. plz post.
regards

Exception obtained when invoking a web service generated with JDeveloper

Hello,
I tried to create a synchronous BPEL process that invokes synchronously a Java Web Service created with the JDeveloper. The web service is wrapped around a regular Java class. The new created BPEL process is successfully compiled and deployed on the server. But when I try to initiate a test instance of the process in the BPEL console, after I fill the input parameter for then process and push the "Post XML Message" button, I obtain the following error:
Your test request generated the following exception/fault:
BPEL Fault: {http://oracle.com/cde/util/Top300DAO.wsdl}org.apache.wsif.soap.fault{org.apache.wsif.soap.fault.object=java.net.ConnectException: Connection refused: connect}
I looked at flow and it throws the exception when it tries to invokes the web service generated with JDeveloper.
Do you have any hints, ideas? Thanks a lot in advance for your help.
I want to also say that the proxy settings for the BPEL server and designer are filled. I think that they are ok because I succeeded to start an instance of another process that calls synchronously an external Web Service.
Regards,
Marinel

My guess is that this is caused by the WSDL of your service having an invalid service address. Can you please take a look at the WSDL of your service make sure that the location of the address is valid? (we have seen a couple of instances in the past where the generated url did not have the right port information).
Update that WSDL, restart the BPEL server or from the BPEL console clear the WSDL cache and re-initiate your flow.
Best,
Edwin

TOC Does Not Open in WebHelp Generated with RoboHelp 11

The TOC does not open in WebHelp Generated with RoboHelp 11. I tried other solutions posted on this forum but no success. Any ideas? Thanks in advance for your assistance.

Hi Jeff,
Thanks for responding! I uninstalled and reinstalled RoboHelp 11 and the WeHelp appears to display OK now. BUT, I have graphics in my project that are not displaying, only the empty placeholder for the graphics. This was displaying fine in WebHelp generated with RoboHelp 9 but not now. I see the graphics when I do “Preview Topic” but not in the generated WebHelp. Any clues what is causing this behavior? How can I correct it?
My tables appear very strange too. They are the default table in RoboHelp with the raised gray/silver border. However, in WebHelp, the tables appear as double solid black lines for the border. The tables appear fine in the topic but when viewed via “Preview Topic” and WebHelp output, they are double black likes. Help!
Another thing is that I also get an occasional message about a topic that says “The reference to the file contains illegal characters and will not be shown in Project Manager. How can this be? My css is valid and I use it in numerous help projects.
Once again, thanks so much for your willingness to help. It is much appreciated.

Created a pdf file showing a graph generated with CL_GUI_CHART_ENGINE

Hi Experts!
Please, anyone has already created a pdf file showing a graph generated with CL_GUI_CHART_ENGINE??
Could anyone help me with this requirement?
Thanks in advance,
Best regards

Hi,
I searched and found another solution, because with the code from the link above I got everytime a short dump, maybe I did something wrong.
The solution works with Adobe Form
1. I used the class cl_igs_chart_engine to create a chart with my data and customizing to get the binary data of the image.
2. Convert the binary tab to xstring.
3. You can use this xstring on the Adobe Form to display the image.
Maybe the following tips are useful.
*How to get the data of chart you can see in the class
CL_TIME_CHART_SIMPLE (use cl_gui_chart_engine for the chart but class cl_igs_chart_engine for saving the image)
*How to bind the image to the importing parameter (xstring)
